Equations describing stimulated Brillouin backscattering including absorption in the media are solved by the method of integration along the characteristic equations of the fields. More complete analytical expressions for pump and Stokes wave intensities and for the width of the backscattered pulse are obtained. A comparison between theoretical and experimental data is made to explain the pulse compression.
